Can Freon go low without a leak?

Refrigerant is not consumed or used up in normal day-to-day operations, but some cars due exhibit a slight loss over time. While some will argue that on the molecular level no system is completely sealed, when your vehicle leaves the factory, its air conditioning is essentially leak free.

Does refrigerant go bad?

That's because refrigerant simply does not go bad or expire. As long as the cylinder or can is fully sealed (no leaks) and the valve is not open or broken, refrigerant will last in its container indefinitely. If intact, the can/cylinder is a sealed unit and will not deplete or leak refrigerant.

Why are old Freon so expensive?

SUPPLY & DEMAND

What little Freon is made has become so rare that the prices have skyrocketed. Much of the Freon you can buy today is actually reclaimed, meaning it was extracted from an old system before disposal. Since the supply is so low, but demand still remains fairly high, Freon prices are jaw-dropping.
